CARL E. TIDEMAN, OF WORCESTER; MASSACHUSETTS, ASSIGNOR TO BURLINGAME MACHINE COMPANY, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSA- CHUSETTS WIRE-DRAWING MACHINE Application filed may 25, 1927. Serial No. 194,198.

This invention relates to a machine for drawing wire through a series of'dies continuously. The principal objects of the invention are to provide improved driving. means for the machine in which the drawing through drum is driven positively and the winding drum is driven in such a way that it can be stopped independently of the drawing through drum; to provide a machine in which the horizontal and vertical types are combined ;to provide an improved location of the respective parts of the machine so as to provide the necessary parts in a comparatively small space, and ,to provide other improvements and advantages which will be described below.

Reference is to be had to the accompanying drawings in which Fig. 1 is a plan of a wire drawing machine constructed in accordance with this invention;

Fig.2 is a side view; and

Fig. 3 is an end view with the means for driving the winding drum in section.

The machine is shown as mounted upon a frame 10 which has a horizontal driving shaft 11 driven through a pulley 12. This shaft is provided with a pulley 13 fixed thereon, which, by a belt 14 passing over idlers drives a pulley 15 on a vertical shaft 16. This shaft 16 is in two parts adapted to be connected and disconnected by a clutch 17 operated by a handle 18. To the upper part of the shaft 16 is secured the hub of the winding drum 20. The shaft has a bearing in the frame and is supported on the top of this vbearing by a collar. It also has a collar below to prevent vertical vibration.

On the shaft 11 is a clutch 25 which connects it with a shaft 26 in line with it on which is a gear 27 driving a horizontal parallel shaft 28 through another gear. On this shaft is the solid conical drawing through drum 29 which is providedwith a series of grooves in the usual way for drawing the wire. It is driven positively from the shaft 11 when the clutch is in.. The clutch is operated by a handle 30. p I

Supported on the side of the frame over a trough 31 for the cooling solution is a conical idler drum made up of a series of grooved discs 32 and separating plates 33. These are mounted to turn freely on a horizontal shaft 34-which is supported on bearings on the frame and located above the trough 31. Its

wall has a series of passages for the wire behind which are located the dies 37. This trough has a series ofpartitions dividing it into compartments draining into one another I as they are located at different levels.

Supported on the frame. beyond the trough 31 is another die holder 39. This die holder can be used for holding a diewhenever it is desired to draw wire dry, that is without the use of a solution.

On the shaft 11 is a sprocket driving a chain 40 which operates a pump41 for conducting a solution through a pipe 42 and applying it to the wires through a perforated pipe 43 to which it extends. The solution is deposited on each wire in a stream while they are on the drum 29 or just as they are passing I to it.

It will be seen that in the operation of the machine the single wire comes in from the left as shown in Fig. 1 and passes around one of the discs 32 and then is fed to the drum29 around which it passes twice. Then it goes back around another disc132; This operation is repeated over and over and the'wire finally passes to the winding drum v20. The discs on the drum 32 are rotatable independently and are not rotated positively, while the drum 29 is in a single piece rota-ting positively. The drum 20, being operated through a belt, is not turned with" absolute positiveness, al-

though the effect is the same, except when The .drum 29 coning the drums 29 and 32 rotate on horizontal axes and the drum 20 on a vertical axis, some of the advantages of the horizontal and vertical machines can be retained and the ma- 1 5 chine will occupy a minimum of floor space. Y

Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to the details of. construction herein disclosed, but what I do claim is: I In a wire drawing machine, the combina tion with a drawing through drum and a winding drum, of a power shaft, positive means for driving the :drawing through drum from the driving shaft, means for disconnecting said positive means from the power shaft, belt driven means for driving the winding drum from the power shaft independently, and means for disconnecting the winding drum from the power shaft, so

' that either the winding drum or the drawing through drum can be operated independently In testimony whereof I have hereunto affixed my signature.
